Searching for vital information is one of the most important aspects of any modern computer application.

Today a widespread problem inherent in the interactive search process is inefficient search functionality.

The dual challenges of substantial volumes of accumulated information on one hand, and increasingly complex and demanding customer needs on the other, has necessitated the development and employment of smarter search method algorithms in search engine software.
The very notion of a net search today is significantly different from its original interpretation; The notion of times past being a comparison of explicitly stated input data, against explicitly identifiable records stored in the database.

Clients today submit a request containing the search context, which for a number of reasons may significantly differ from the data corresponding to the information that is stored in the database. The search query, for example, may contain syntax and grammar errors, a word may be dropped, or represented in different order, and may include extra information. Additionally, input information provided by the client may even be unavailable in the database, having only its close semantic equivalent.

A user may not remember the exact name of an electrical device from its hundreds of varieties, nor have the physical address of a shop or bar he never visited.

A user may not remember the name of an individual he met five years ago at a party, or remember a particular brand name of a car, or any other item of interest for that matter.

A client composing his request must often draw from very limited information in his mind. Submitting such a "fuzzy" request, the user expects to receive a reasonable number of found results, reasonably close to his conceived idea, and sorted by some meaningful relevance.

Standard tracing mechanisms built into typical modern databases do not deal with this problem, yet this is the most pressing problem which needs addressing in today’s modern commercial applications.

Even the best designed product/service is unlikely to achieve commercial success unless prospective customers have the freedom to easily search for the product/service they seek in less than explicit terms.
